The flag of Saudi Arabia has a green field with large white Arabic writing above a white horizontal sword (the tip of the sword points to the hoist side of the flag). The Arabic writing is the Islamic statement of faith, "There is no God but Allah and Muhammad is his Prophet." Green is the traditional color of Islam.

Saudi Arabia's flag was adopted on March 15, 1973. The flag's design was based on the flag that represented the army of Abdul Aziz Ibn Saud, the first King of Saudi Arabia.
